Background:
Dapsone is a synthetic sulfonamide used to treat numerous dermatologic conditions. Ocular side effects have been rarely reported and include retinal necrosis, optic atrophy, and macular infarction. We report the first known case of bilateral choroidal effusions and exudative retinal detachments associated with dapsone use.
Case Presentation:
A 57-year-old male with a past medical history of testicular seminoma presented with bilateral blurry vision for 2 months. His exam revealed bilateral choroidal effusions with bilateral exudative retinal detachments without evidence of intraocular tumor. The patient had recently been prescribed dapsone for urticarial vasculitis. The patient was instructed to discontinue dapsone and follow-up closely. Interval follow-up of 8 months demonstrated almost complete resolution of the choroidal effusions and retinal detachments with residual pigment epithelium changes after cessation of dapsone. The patient recovered his pre-detachment visual function.
Conclusions:
Patients on dapsone who present with new visual complaints should undergo a thorough ophthalmic evaluation given the multiple mechanisms by which dapsone can affect the eye.
